What causes numbness and stiffness in hands and feet when excited, and what should be done about it?

Numbness and stiffness in the hands and feet during emotional excitement may be caused by physiological factors, or pathological conditions such as cervical spondylosis or hypertension. Treatment—whether surgical or medicinal—should be determined based on the specific underlying cause. Detailed analysis is as follows:

1. Physiological Causes

During emotional excitement, the brain is in a state of heightened activity, leading to accelerated blood circulation. Some patients may experience numbness or stiffness in their hands and feet. This is a normal phenomenon and typically does not require treatment.

2. Pathological Causes

1) Cervical Spondylosis

Cervical spondylosis can affect and compress the cervical nerve roots, causing reactive edema in the nerve roots and surrounding tissues, along with narrowing and adhesions in the spinal canal, resulting in numbness in the fingers. This condition can be treated surgically.

2) Hypertension

In patients with hypertension, fluctuations or increases in blood pressure can lead to spasm of small arteries throughout the body, narrowing of blood vessels, and localized insufficient blood supply to the hands and feet, thereby causing numbness in the limbs. Medications such as nifedipine controlled-release tablets or amlodipine besylate tablets may be taken as directed by a physician.

In addition to the common causes mentioned above, numbness may also result from diabetic peripheral neuropathy, myelitis,stroke, and other conditions. It is recommended that individuals experiencing such symptoms seek timely medical evaluation and treatment.
